A dust collection electrode with catalyst to be provided on the electronic dust collector is manufactured simply at low cost without using a furnace. To the surface of the metal tube of the sheathed heater a low temperature curing type heat resistant inorganic adhesive is applied. Thereafter, a catalyst such as Zeolite is adhered to the heat-resistant inorganic adhesive. Next, the sheathed heater is energized to make self-heating, and using said heating, the heat-resistant inorganic adhesive is heated to cure, thereby fixing the layer to the surface of the metal tube.
